Question

if we want to provide a 95% confidence interval for the mean of a population, the confidence coefficient will be group of answer choices 1.96. 1.645. .485. .95.

Answer 1

If we want to provide a 95% confidence interval for the mean of a population, the confidence coefficient will be: D. .95.

What is a confidence interval?

A confidence interval is also referred to as level of confidence and it can be defined as a range of estimated values that defines the probability that a population parameter would fall or lie within it.

For instance, the confidence interval at 95% is given by p - E < p < p + E

Since the confidence interval for the mean of a population is at 95%, the confidence coefficient would be calculated by simply dividing the confidence interval by 100:

Confidence coefficient = 95/100

Confidence coefficient = 0.95
